BEVERAGE DI SPENSER Filed July 24, 1967 Sheet 4 of 4 ATTORNEYS United States Patent US. Cl. 62-390 2 Claims Int. Cl. B671] /62 ABSTRACT OF THE DISCLOSURE A dispenser for dispensing cooled beverages which is designed for mounting on a serving counter. It has cooling coils and a number of valves designed to selectively direct beverage flavourings and water through the cooling coils to dispense a beverage. By selection of the valves, cooled beverages and different flavours and strengths can be mixed and dispensed.

The dispenser has the refrigeration unit assembly mounted on a deck that has a depending leg structure which is designed to support the refrigeration unit assembly in an operative position and also designed to support the refrigeration unit assembly when it is removed from the dispenser for service. The supply conduits to the product cooling coils are formed in a U-shape that extends up the exterior of the cooling tank over the top edge of the cooling tank and then downwardly into the cooling tank to merge with the coil of the cooling tank so that they can be easily serviced.

This invention relates to a device for dispensing beverages. More particularly, it relates to improvements for such a device that makes it easier to service.

Beverage dispensing devices having manually controlled spigot valves for drawing and mixing a cooled beverage from a pressurized supply of soda water and flavouring or water and flavouring are known. They are extensively used in restaurants, refreshment booths and the like. They frequently require service and, with rising costs of labour, economical service is becoming difiicult to supply. This invention relates to design improvements in these units that makes service easier and therefore less costly. The improvements also add to the simplicity of the unit and tend to require less service.

It is an object of this invention to make a beverage dispenser that is easy to service.

It is also an object of this invention to make a beverage dispenser that is simple and therefore requires less service.

A beverage dispenser of the type to which this invention relates has a base, an insulated cooling liquid tank carried by the base, an electrically operated refrigeration unit bodily mounted on the base having refrigerating coils in the cooling liquid tank, a plurality of product cooling coils extending into the cooling liquid tank, a plurality of product supply conduits in said base, a plurality of product dispensing valves rigidly mounted with respect to the base, each having inlet means for connection with said product coils, connecting means connecting said product cooling coils with said supply conduits and with said product dispensing valves to controllably dispense product supplied through said supply conduits. A beverage dispenser according to the invention has supply conduits that terminate exteriorly of the cooling liquid tank for connection to the lead in section of a product coil, the lead in section of each product coil extending exteriorly of the cooling liquid tank. The invention will be clearly understood after reading the following specification in conjunction with the drawings.

In the drawings:

FIGURE 1 is a perspective view of a beverage dispenser according to the invention;

FIGURE 2 is an exploded view of the principal parts of the dispenser;

FIGURE 3 is a view along the line 3-3 of FIGURE 2;

FIGURE 4 is a fragmentary view showing the refrigeration unit sitting on the cooling water tank;

FIGURE 5 is a view of two concentrate product supply coils, the tubular body portions of the coils being indicated only by lines; and

FIGURE 6 is a view similar to FIGURE 5 showing the product supply coil for the soda water.

Referring to the drawings, the numeral 10 generally refers to a beverage dispenser according to this invention. It has four spigot valves 12, 14, 16 and 18 which are manually operable to dispense a cooled flavoured beverage from pressurized supplies through supply lines 20, 22, 24, 26, 28 and 30. The dispenser has an electrically operated refrigeration unit.

The dispenser has a metal base 34 upon which is mounted an insulated cooling liquid tank 36 and from which extends cooling mounting posts 37, 39, 41 and 43. Cooling liquid tank 36 is formed from a pair of met-a1 tanks, one within the other, with insulation 38 in the space between. It is adapted to hold refrigerated water and beverage is conducted through cooling coils that extend through the tank, as will be referred to again later.

The numeral 40 generally refers to an electrically operated refrigeration unit assembly which is bodily mounted on the base 34 to dispose the refrigerating coils 42 thereof in the cooling liquid tank 36, as illustrated in FIGURE 3, for the purpose of keeping the cooling water cold. The refrigeration unit has a deck 44 with depending support legs 46 which are adapted to straddle the cooling liquid tank 36. The working parts of the unit, which generally comprise the refrigerating coil 42, the condenser radiator 48, a cooling fan 50, a motor compressor unit 52 and associated control boxes 54 and 56, are all suitably mounted on the deck and electrically wired according to standard practice. A temperature sensing device 57 depends into the tank 36 to operate the unit automatically to control the water temperature. No novelty in respect of the refrigerating working parts per se is claimed. They are well known. However, the particular design of the deck 44 with its depending support legs which straddle the cooling water tank 38 to stand on the opposed base supports 58 to dispose the refrigerating coil 42 in operative position is of importance. It will be noted that the foot of the legs 46 depends a greater distance from the deck than the bottom of the refrigerating coil 42. Thus, when the refrigerating unit is removed from the base for service, the legs 46 function to support the unit in a vertical position on a flat surface with the refrigerating coils protected and supported in a vertical position. Legs 46 are secured to their support base 58 by means of bolts.

In use, water in the cooling water tank 36 is automatically cooled by the refrigerating coil 42 of the refrigerating unit and product is passed through product coils that extend around the refrigerating coil 42 to cool the product prior to being dispensed from the spigot valves. In the embodiment of the invention illustrated, there are six product coils which are arranged into an assembly 60 and clipped together by hair-pin type clips 62 and placed in the cooling water tank 36 extending around the refrigeration coil 42.

Five of the coils are similar to the coils 64 shown in FIGURE 5, wherein two single turn coils have been illustrated, and have a lead in section 66 and a delivery section 68. The lead in section 66 of each coil connects by means of a manually releasable fitting with the terminal end of one of the supply conduits 20 as at 72. The delivery section 68 of each coil connects by means of a manually releasable fitting with the input to a spigot valve as at 74.

The sixth coil 76 is similar in its connections with the exception that it has more turns and, at its upper end, it terminates in a manifold section 78 whereby it can be connected by releasable fittings, similar to the fitting 72, to each of the valves 12, 14, 16 and 18. This particular coil carries soda water and it has more turns because it constitutes the greater :bulk of a dispensed beverage and requires more cooling capacity.

Product supply conduits 20, 22, 24, 26, and 28 and 30 each have fittings for manual connection to supply lines that in use extend to pressurized supplies of beverage components.

Product coil 76 connects with a pressurized supply of soda water and leads to all dispensing valves. One of the five product coils 64 connects with a pressurized supply of water and with valve 12. The other four product coils 64 each connect with a flavoured beverage concentrate and with one only of the valves 12, 14, 16 and 18. By manually manipulating the spigot valves, one can draw a mixed beverage consisting of concentrate from a selected concentrate supply and soda water and/or water. The valves and their manipulation and the general beverage circuit are not novel and form no part of this invention. Valve 12, which will mix concentrate and water or concentrate and soda water, can be a valve comn1ercially known as a TMLClW McCann Valve. Valves 14, 16 and 18, which only mix concentrate and soda water, can be a TMC11 or a TMC-lO valve. These things are very common practice in the beverage dispensing art. The number of coil turns can vary depending on design. Their function is to give the product sufiicient passage time in the cold water to cool it. The water supply coil preferably has more than one turn.

However, the particular design of the product coils 64 and 76 in respect of the manner in which they are connected into the circuit is novel and important because it permits very efiicient removal of the product cooling coils for service. These coils are preferably made from a non-toxic metal, such as stainless steel, and their lead in sections releasably connect with the termination of supply conduits on the exterior of the cooling liquid tank 36. They extend over the upper edge of and down into the cooling liquid tank. At their delivery sections they releasably connect with the dispensing valves. It will 'be apparent that by first removing the refrigerating unit, one can easily disconnect the product coil assembly and remove it without draining the tank or manipulating fittings on the tank.

The deck 44 of the refrigerating unit 40 also carries an agitator assembly that includes a motor 80 having a shaft that extends into the cooling liquid tank and has an agitator 82 on its free end. Motor 80 continuously operates to circulate the water in the cooling liquid tank in use. This is a known expedient. Cooling liquid tank has an overflow drainage outlet 79.

The underside of deck 44 has a resilient gasket 45 that seals around the top of the tank 36 and that yields at the places where the product coils cross the top of the tank, as shown in FIGURES 3 and 4, when the refrigeration assembly is mounted in place.

To assemble the dispenser the product cooling coils are arranged, clipped together and their ends are connected to the appropriate supply conduits and spigot valves. The self-supporting refrigerating unit 40 is then lowered into position on the supports 58 and it is bolted into position.

Electrical supply for the refrigerating unit including motor 80 is through plug supply 84 that plugs into electrical receptacle 86 that is carried on a cowling secured to the base. Plug-in receptacle 86 connects by conduit with a source of electrical power.

The working parts are covered by cowlings which are especially easy to mount and take off. The spigot valves and the electrical receptacle are bolted on a bottom front plate 90 that is 'screW held in position by screws 92. B'ackplate 94 is similarly held in position.

All other side cowlings are vertically slid into position. They are formed with side edges or hook means that cooperate with posts 37, 39, 41 and 43 whereby they can be simply placed into position and/ or lifted out of position.

The side cowlings 96, 98, and 102 are each formed with an inwardly extending channel that embraces the posts 37, 39, 41 and 43 and they are dropped into position. Upper panels 104 and 106 have a channel shaped bracket that embraces the opposed edges of opposed posts as they are slid into position. The top panel 108 rests in place.

Upper front panel, upper back panel and top panel are open grills to permit escape of heat from the refrigerating unit.

It will be noted that a drainage trough 110 is mounted in the base beneath the drain board 112 and that it has means for an external drain connection. Numeral 113 is a tap for draining the cooling water tank.

The unit as described above is used to dispense drinks from supply sources external of the unit. The drink ingredients are cooled as they pass through the cooling liquid tank prior to being dispensed through the spigot valves. The valves, their operation to dispense a drink upon manual manipulation, the general product flow circuit are all well known and do not form part of this invention. This invention is concerned with making a unit of known general type that is easier to service and this objective has been achieved by a number of features in combination. The cowlings are easily removable and replaceable. The product cooling coils are simple in design and can be simply disconnected by two connections exterior of the cooling tank. The product cooling coils are continuous and pass over and not through the tank wall and are therefore not only easier to service but should require less service. The refrigeration unit is bodily removable and can support itself in a vertical position on a flat surface when removed for service without danger of damage to coil or other parts.

Embodiments of the invention other than the one shown will be apparent to those skilled in the art.
